1. Product Highlights 1.1. Plexiglass outer shell, beautiful design and generous, key touch texture is good, press the button to set the output voltage, eliminating the need to use a knife; 1.2. The button can control the output to turn off and on, and can set the product power-on default is ON or OFF; 1.3. LCD can display input and output voltage, output current, output power; 1.4. Input reverse polarity protection, reverse connection will not burn; 1.5. High efficiency over 93%, large current, small heat, output voltage 1.2-32V arbitrary regulation, constant current value of about 0-4.5A adjustment, suitable for office power, high-power LED constant current drive, lithium battery charging and so on! 2. Product parameters Input voltage: 6.5-36V (input voltage less than 6.5V, current is not accurate, less than 5.5V, LCD display is not normal) Output voltage: 1.2-32V, factory default output 5V. Output current: Can work stably at 3.5A for a long time, and can reach about 4.5A under enhanced heat dissipation (adjustable limit current is about 4.2-4.5A) Output power: natural heat dissipation 50W (less than 3.5A), enhanced heat dissipation 75W Voltage display: resolution 0.05V, range 1.2-32V, accuracy of about 0.1V (accuracy demanding carefully shot!) Current display: resolution 0.005A, range 0-4.5A, accuracy 0.05A (precision for those who require strict accuracy!) Conversion efficiency: about 94% Working current: about 30mA Reverse input protection: Yes Anti-backflow at the output end: None (If the battery is charged, first power on the module and then connect the battery, and ensure that the battery voltage is lower than the output voltage; if the condition is required, connect the anti-backup diode to the positive side of the output string) Short circuit protection: Yes Size: length * width * height 70.5*48.4*28mm
